Honest question for everyone putting Winter Soldier on their lists: why do you consider him a villain? Not trying to start an argument, I'm just legitimately curious. Because if Bucky is a villain in TWS, then you might as well also call Hawkeye a villain when he was under Loki's control in Avengers. I'd even go so far as to say that Nebula has been shown to be more villainous in the MCU than Winter Soldier (at least from GOTG 1, a little bit in Vol. 2 and her 2014 self in Endgame) and she's never brought up as much as he is in MCU villain conversations.
